Recently, Jinshazhou Hospital of Guangzhou University of Traditional Chinese Medicine (hereinafter referred to as Jinshazhou Hospital) has introduced a Varian Ethos medical linear accelerator, which represents the latest tumor radiation therapy technology with high intelligence. Completed the hoisting and entered the commissioning stage. It is understood that the Ethos introduced by Jinshazhou Hospital is the first in South China and the third one installed in China.
Radiation therapy has the characteristics of painless, non-invasive, and local targeted treatment, and is one of the main methods of tumor treatment at present. According to the report of the World Health Organization, about 70% of cancer patients need to receive radiotherapy, of which 40% of tumors can be cured by radiotherapy alone, which is only slightly lower than that of surgery (49%). With the development of tumor clinical medicine, radiation therapy plays an increasingly important role in tumor treatment.

“Compared with conventional linear accelerators, this intelligent linear accelerator has an innovative new mode of adaptive radiation therapy, which can achieve a The high-definition iCBCT images of the treated tumor target area during the daily treatment process, through AI intelligent assessment, automatic adjustment and recalculation of the daily irradiation dose, the whole process only takes a few minutes to complete, and before this It will take at least two or three days.” According to Professor Wang Yang, Vice President of Jinshazhou Hospital of Guangzhou University of Traditional Chinese Medicine, Executive Director of International Cancer Center and Director of Radiotherapy Department, the newly introduced Ethos medical linear accelerator is fast, accurate, comfortable, The four major features of safety are a revolutionary new generation of radiotherapy equipment, and its application has brought precision radiotherapy a big step forward.
Xiaping Wei, Deputy Director and Chief Radiation Physician of Jinshazhou Hospital Radiation Oncology Center, said that the new mode of adaptive radiation therapy of Ethos Medical Linear Accelerator is powered by deep learning and driven by multimodal imaging. , on the basis of the original treatment plan, according to the changes in the shape, volume, size, and location of the tumor, it can be softly adjusted from imaging, delineation, plan design to treatment implementation within a few minutes, which is equivalent to each treatment. It is a mature application of personalized and intelligent artificial intelligence technology in the field of radiotherapy that the patient re-tailored a treatment plan that is most suitable for the current physical state. “The online adaptive system is suitable for precise radiotherapy of tumors, especially for tumors located in the pelvis, such as cervical cancer, prostate cancer, colorectal cancer, and bladder cancer, whose position is likely to change greatly with body position.”

It is reported that the newly added Ethos will work with other top-level radiotherapy equipment already in clinical operation in Jinshazhou Hospital, including the country’s first M6 Cyberknife radiosurgery robot, the use of helical The radiotherapy equipment TOMO for the treatment of cancer by tomography, and the world’s top linear accelerator TrueBeam (commonly known as “radiotherapy superman”) form a complete combination of tumor diagnosis and treatment equipment, making radiotherapy more intelligent and precise.
